Hi Skilpad and thank you for answering.
The 5-way selector has four contacts on one side and four contacts on the opposite side.
The alleged DPDT switch is three position switch and i must unsolder the wires to check using a multimeter.
If you take a look
http://www.guitarnuts.com/wiring/sw3.php the way the wires are soldered now, it looks like and OnOffOn and not an OnOnOn..
I don't mind going for new material :) Sometimes, it's better to go for new parts.
The sound I want? It's a difficult question to answer. I think it's a bluesy vintage sound with smooth overdrive, but I also use an old RAT for my distorted powerful sound.
Edit: I 'm looking into something like DiMarzio EP 1108 for DPDT switch, DiMarzio EP 1112 for 5-way selector and three new pots for volume and tone (500k maybe?)
I've seen that BK has also parts like these available but to be honest I don't know anything about them.
